Dear Sir:

Three Mile Island Iiuclear Statien, Unit 1 (3!I-1)

Operating LL:ense :i0. DPR-50 Docket IIo. 50-2c9 Please be advised that the OII dike and riprap repairs referenced in cur letter of Septecter 29, 1975, have teen ec=pleted and inspected except as noted belev:

1.

Additional toe protection between the intake structures has been placed, but since the additional material is submerged and no inspec-tor was on site to verify the placement, it vill be necessary to verify placement with a beat and sounder.

It is planned to perform this check concurrently with the June Rydrographic Surve/.

2.

The riprap material placed into the depression between the structures appears to be slightly lighter than specified,but since this is above the design flood level no corrective action is planned.

'4e trust this resolves any concerns you have had and should you have any further questions, please contact me.

Sincerely,

(
